Acid and alkali resistant PTFE dust bag

是采用非织造针刺工艺利用纤维交错排列，空隙分布均匀的细纤维布，以涤纶短纤维与涤纶有捻纱所生产的针刺毡表面经热轧、烧毛或涂层等后处理，使其表面平整光滑，不易被粉尘所堵塞，此滤料空隙率大，透气性能较好，用途极为广泛，抗化学稳定性强，不仅可以过滤常温气体，而且可过滤含有酸碱的腐蚀性气体，并可滤水、滤油、是常温工况，液固分离等领域理想的过滤材料。Acid- and alkali-resistant PTFE dust-removing cloth bagis a fine-fiber cloth with non-woven needle-punching technology that uses fibers staggered and uniformly distributed. After the layer is processed, the surface is smooth and smooth, and it is not easy to be blocked by dust. The filter material has a large porosity, good air permeability, a wide range of applications, and strong chemical stability. It can not only filter gases at room temperature, but also filter acid. Alkali corrosive gas, and can filter water, oil, is an ideal filter material in normal temperature conditions, liquid-solid separation and other fields.The polyester needle felt is a stiff and short fiber filter with uniform pore distribution and a porosity of 70%, which is double the woven filter cloth.High dust removal efficiency and low gas emission concentration.The surface of polyester needle felt is hot-rolled and scorched or coated to make it smooth and smooth. It is not easy to be blocked, deformed, and easy to clean. It has a long service life.Anti-static needling felt has the function of preventing the electrostatic discharge of blast furnace gas and coal mill bag dust from the cement plant and discharging static electricity.Needle felt filter bags have the advantages of common felt filter cloths, such as high air gaps, good air permeability, high dust collection efficiency, and long service life.It has a moderate temperature resistance level, which can reach 150 ° C in an instant, moderate acid and alkali resistance, and has very good abrasion resistance.
